LOAD CARRYING CAPACITY OF PILED –RAFT SYSTEM USING NUMERICAL APPROACH by Himani Chawla 

Abstract

The foundation system is an important component from the civil engineering point of view in general and it is the duty of geotechnical expert to take care of the safety and stability of foundation of civil engineering projects. The pile raft foundation system is a composite foundation which contributes the involvement of piles, raft, and soil to transfer heavy loads of the superstructure to the ground. The utilization of piled-raft system is an efficient way of reducing both total and differential settlements, enhancing the bearing capacity of a foundation. The analytical work includes the numerical analysis of pile raft foundation under the effect of variable ground water table by generating a numerical model in FEM based PLAXIS 3D software. As piled-raft foundation system is the main concern of its effectiveness because it is the most refered foundation system especialy for the high rise buidings . The relevence of the system comes when one system works efficiently under the adverse subsoil condition at the cheaper cost than the other foundation system. Adverse subsoil conditions comes when the foundation system was encountered with ground water table.The bearing capacity of the saturated soil reduces to about 50% of its orignal bearing capacity in its dry state.The large reduction in the bearing capacity is the serious concern for the geotechnical engineers. So here comes the need to analyse the effect of ground water table on the foundation system.In this study an effort has been made to analyze the experimental results of piled raft using PLAXIS 3D software.With the experimental investigation it is very difficult to study the effect of ground water table variation on the load carrying capacity of the piled raft but using the FEM based PLAXIS 3D this problem can be addressed easily. The study highlights that there is significant reduction in the ultimate load (decreases from 7731.29kN to 5659.68kN when there is rise in ground water table from great depth to ground surface

STRENGTH IMPROVEMENT OF CLAYEY SOIL BY USING FLY ASH AND MARBLE DUST by Amandeep Verma

Abstract

Strength improvement of soil means that to improve the properties of soil by different methods. Some

waste materials are used to improve the soil such materials are fly ash, marble dust. Fly ash is the ash

produced by burning of pulverized coal in thermal power plans. Marble industries are producing larger amount of marble dust. The rapid growth of marble dust creates a big problem on environment as acts as a pollutant and affect the ecological system. Hence both material are cheap by cost. The object to carry out this study was to evaluate the effect of materials i.e marble dust and fly ash when mixed with clay soil. The physical and chemical properties of soil was improved by addition of such those materials. Whereas some expecting properties are index properties, compaction characteristics and strength properties. The marble dust is added in range of 5–20 % in corporation with fly ash 10-30%. Laboratory studies were performed to identification the Atterberg limits, proctor density, Unconfined compression strength, triaxial test. It was found that addition of 20% fly ash in soil shows maximum strength value increases 114.42% Unconfined compression strength(UCS). Further addition of fly ash has negative effects on these properties. Triaxial test is performed to calculate shear strength parameters of mixed soil i.e soil, fly ash and marble dust. It was found that cohesion character (‘c’) goes on decreasing and angle of internal friction (φ) goes on increasing by addition of marble dust in soil and optimized fly ash.

PRETREATMENT OF TEXTILE INDUSTRY WASTEWATER USING NATURAL  OAGULANTS by Mandeep Kaur 

Abstract

The textile industry consumes large quantities of water and produces large volumes of wastewater with high color, turbidity, BOD, COD, suspended solids, sulfide, chlorides and heavy metals. Untreated effluents when discharged directly into the open lands or into water bodies can cause irreversible harm to the environment. Coagulation is the most important physical and chemical treatment used in industrial wastewater treatment to diminish the various wastewater parameters. Now a day, more interest has been given on the pretreatment of wastewater coming from industries with natural coagulants because natural coagulants are relatively cost-effective as compared to chemical coagulants. As moringa oleifera and cactus are easily available, they are used as natural coagulant in this research to reduce color, turbidity, nitrates, chlorides, fluorides in dyeing wastewater. Sharman spinning mills is a textile industry which was selected for work and is situated in Ludhiana. The wastewater generated during dyeing process was collected from textile industry. The coagulation of wastewater was done with jar test apparatus was carried out using natural coagulants. Optimum dosage and optimum pH were determined after intensive lab scale testing. The pH value of 10.5 was found to be more efficient for removal of chlorides, nitrates, fluorides for both coagulants, whereas in case of turbidity and color efficient pH was found to be 3.5, but pH 10.5 was considered to be optimum pH because there was significant removal of wastewater parameter characteristics. Similarly the optimum dosage of cactus and moringa oleifera for efficient removal of all parameters was found to be 0.6gm/500ml at pH 10.5.

TECHNICAL PARAMETER ESTIMATION AND COST ANALYSIS OF A MODELED SOLAR POWER PLANT (CASE STUDY) by Ramanpreet Kaur 

Abstract

The world energy consumption is the main matter for the social and political aspects. The power generation using conventional sources like coal, oil, and gas is mostly preferred for large capacity plants over the years. These sources cause emissions and due to the depleting of fossil fuels, the need is to focus on the renewable energy sources. The second main reason behind using renewable energy sources is fuel cost. Global warming is caused by human activities. Every country’s government takes efforts to reduce emission. The rising prices are also causing instability. Therefore, it is beneficial to use PV solar system to meet the power demand. Availability of renewable sources at large distance locations recommends grid integration for easy and reliably transmits power. For designing of a uitable solar PV plant it is necessary to estimate techno, economical parameters of the plant.

Abstract

Soil plays very important role for obtaining the good civil engineering structure such as roads, buildings etc. because the whole structure depends upon the subgrade of soil. But mostly the problem arises due to poor soil that does not have good engineering properties. So to overcome this problems soil stabilization plays a vital role and it has become necessary before the constructions at the site. The research is done to study the impact of Jute fiber and Cement kiln Dust on soil stabilization. The soil samples were made with Jute fiber and Cement Kiln Dust at different proportions and tests were conducted. The result shows that there was improvement in engineering properties of soil. There was increase in the maximum dry density of soil as the percentages of Cement Kiln Dust were increased. With increase in proportions of CKD in the soil there was decrease in the value of optimum moisture content. The research shows decrease in the maximum dry density as the percentage of Jute fiber was increased and increase in optimum moisture content as the percentage of Jute fiber was increased. In this research different proportions of Cement Kiln Dust (5%, 10%, 15%, 20% and 25%) and Jute fiber (0.25%, 0.50%, 0.75% and 1%) were mixed in the soil and the optimum quantity was obtained after performing series of soaked California Bearing Ratio tests. The optimum quantity of Cement Kiln Dust and Jute fiber was 20% and 0.75% that was obtained in this research. After this the samples were prepared with mixture of soil, Jute fiber and Cement Kiln Dust at optimum quantity. UCS tests, CBR (soaked) tests and Compaction tests were conducted on the samples. The samples were cured for 7 days and 14 days in UCS tests. The results shows that there was increase in CBR value and maximum CBR was obtained at the 79.25 Soil + 20% Cement Kiln Dust + 0.75% Jute fiber content.

Effect of Material Composition on Strength Characteristics of Fly ash Bricks by Harsimranjit Singh 

Abstarct

Bricks are one of the oldest material used in construction industry. Commonly used bricks are made up of clay with certain admixtures. Due to rapid increase in population and to meet its needs, new houses and multi-storey building are constructed in large numbers, which requires large number of bricks for its construction. Thus due to overuse of clay bricks a new material is required to be used for construction of bricks. Fly ash is one of the industrial waste, produced from thermal power plants and which is dumped in open environment and causes environment pollution. As it contains silica which reacts with lime and strengthen the brick, therefore it can be used for construction of bricks. In the present study fly ash bricks were made by using fly ash, sand, lime and Plaster of Paris (POP) in different mix proportions. The brick specimens of size 230 x 110 x 70 mm were manufactured and various quality parameters like compressive strength at an age of 7 and 28 days, water absorption and dry density were tested. The economical mix design of the fly ash bricks for maximum compressive strength and its rate analysis was also done. The results show that strength decreases with increase in fly ash content and increases with increase in sand and lime content in fly ash bricks. Water absorption value increases with increase in fly ash content and decreases with increase sand and lime content in fly ash bricks. Dry density decreases with increase in fly ash content and increases with increase in sand and lime content in fly ash bricks. The maximum compressive strength was obtained for mix percentage of fly ash-38%, sand-33%, lime-24% and POP-5%. Thus it is imperative that fly ash be used purposefully and fly ash bricks provide a good solution.

DETECTION AND SMOOTHENING OF SPECTRAL DISCONTINUITIES IN CONCATENATED SYNTHESIZED SPEECH WAVEFORM by Birpal Kaur

Abstract

In today’s fast developing world the demand exist for applications of computer where the humans can

communicate with computers through speech. Infect instead of giving text commands to computers, humans want to control them through their own voice and also want computers to respond back through voice replies. The foremost purpose of speech synthesis systems lays in production of the synthesized speech from the input text for visually impaired persons, for learning and mastering new languages, various announcements at airports etc. One of the best artificial speech synthesis methods is the concatenative synthesis due to its quality of sound. But it contains some mismatches of spectral nature at the boundaries of joins. The positions where the joins among two speech units are not matched in terms of various spectral parameters like pitch, energy, frequency etc., then the spectral mismatches are observed there. These kinds of mismatches are more audible when the databases are generally small. As in small databases, the number of choices of units present for concatenation is few which lead to mismatches among the various parameters of speech of two joining units. For detecting and removing these kinds of mismatches this thesis work has been carried out. So in order to evade the dilemma of spectral mismatches at various boundaries of concatenation, many algorithms have been purposed for processing the signal and make it smoother. Firstly the mismatches are detected with the help of proposed algorithms and then three algorithms based on various techniques are applied on the synthesized concatenative speech. The results show that after applying these algorithms the final output speech produced is smoother than the original.

A RULE BASED PUNJABI DIALECT CONVERSION SYSTEM by Anterpreet Kaur 

Abstract

At a recent time, informal form of language is surged dramatically on internet resources as web becomes a media for people to share their ideas and thoughts via personal blogs and social articles. In case of Punjabi language, there is deficiency of processing tools for Dialectal Punjabi as compared to Standard Punjabi language processing tools. Our work is the pioneer work which depicts the conversion of three dialects of Punjabi and illustrates the need and complications for Punjabi dialect language. In this thesis work, dialect conversion system has been developed for processing Punjabi dialects namely Majhi, Malwai and Doabi. A rule-based approach is used by proposed system to convert the Standard Punjabi input text into its equivalent Malwai dialect, Majhi dialect and Doabi dialects. To identify Standard Punjabi words in given input text, various methods are used and then selected identified words are converted using rule-based component which has two parts: bilingual dictionary and morphological transfer rules. The proposed conversion system has nine bilingual dictionaries that contains 5,558 words related to Standard Punjabi, Majhi dialect, Malwai dialect and Doabi dialect. These dictionaries are used only for word-to-word mapping but only direct mapping of source text into its equivalent target text is not adequate, so morphological conversion rules for conversion to Majhi, Malwai and Doabi dialects have been developed in thesis that replace specific portion of input word. The transfer rules are implemented on source sentences and then words are replaced as stated by rules. The results of proposed dialect conversion system depict the remarkable accuracy. The accuracy of Standard Punjabi to Majhi dialect, Standard Punjabi to Malwai dialect and Doabi dialect conversion is found to be 96.58%, 96.48% and 97.54% respectively.

AUTOMATIC CLASSIFICATION OF PUNJABI DOCUMENTS USING VECTOR SPACE MODEL by Harsimran Pal Kaur 

Abstract

Now-a-days, a gigantic amount of useful data is generated on web. The information may be in the form of journals, e-documents and web pages. Today, the vast amount of documents are created in every field and to manage and handle these documents, the classification is necessary task. Automatic classification is the process in which the class labels are assigned automatically to the material which is under processing. Automatic classification of documents is an approach that assigns predefined category labels to input text documents. Punjabi is Indo - Aryan regional language spoken by 102 million people. For regional languages there are limited classifiers are available with limited resources. Punjabi Document Classification System receives the unlabelled Punjabi document and assigns it a predefined class label. Automatic Classification of Punjabi Documents using Vector Space Model is performed by converting the documents into set of vectors after preprocessing of documents. Then the document vectors are used to compute cosine similarity. Cosine Similarity is the measure, which defines the class label of input document. The proposed system has been compared with the existing systems which gives 64% and 71% accuracy by using Naive Bayes and Centroid based techniques respectively and both existing systems developed by using Hybrid and Ontology based techniques gives 85% accuracy. Theseexisting systems use 180 documents of different categories for testing and training purposes. The proposed system has been validated by using 517 documents which contains thousands of words and gives 86.84% accuracy.
